Gas Mileage, What are you getting, city/highway? Options

[pbanders]

Yes, it's been done before, but how about an update? I'll go first:

1970 914 w/'74-spec 2.0L D-Jetronic, stock w/Euro pistons, Crane XR-3000 ignition and Crane coil. City: 24 mpg / Highway: 39 mpg (flat road, 75 mph, 80 mile trip)

What are you getting? The 914's a lot better than my '03 Boxster.

Good question. I'd like to figure out what's keeping mine down, other than my right foot. Top off, maybe 24 at best on the hwy, less locally.

I'm kind of in the same boat. To and from work (90% of my driving) I'm lucky to get 20 mpg. That's "parkway" driving where it's 60 mph for a mile or two and then stop for the light. Rinse and repeat. I probably got more like 25 mpg up and back to Hershey, the longest continuous trip I've taken it on.

2056 with stock cam and I might be slightly rich at warm up (using the CHT spacer) but AFR readings are slightly lean, if anything, after that. The only working theories I have now on what may be keeping my mileage down, other than possibly the CHT spacer and the nature of my driving, is my battery has been flaky the last couple of months due to a parasitic drain on it. I'm certain a weak battery doesn't help mileage or performance, but otherwise I'm not sure if I should be doing significantly better or if "it is what it is." I read about you all getting 30+ mpg....
